How BTN opens at 23 BB
When the action folds to the Button with 23 big blinds (8-max MTT with ante), the book plays 42% of hands: a raise to 2 BB with 41% and all-in with 1.7%. The other 58% fold.
Always raised: AA, AKs, AKo, AQs, AQo, AJs, AJo, ATs, ATo, A9s, A8s, A8o, A7s, A6s and 62 more.
Always all-in: 33, 22.
Mixed hands (the book splits them between actions): A9o, A7o, A2o, KQo, JTs, J8o, J4s, T8o, T6s, 96s.
At this depth the open is a small raise, with some hands going all-in directly.
Next to it at 23 BB: CO 32%, SB 88%. Seats closer to the button open more here, because fewer players are left to wake up with a big hand.
Closest decisions (the book opens them only part of the time): T8o 42%, T6s 60%, 96s 60%, J4s 36%, J8o 68%. These are the hands worth drilling, because a small change in the opponents or the stack flips them.
